I'm pretty sure that if you told a cover artist that you book contained a male vampire nowadays, you'd get a broody emo pretty boy in the late-teens to mid-twenties range. But, let us travel back in time to the eighties. I give you Path of the Eclipse.
From the Goodreads summary: China, Tibet, India 1213-1219.
From the background figures on the first one, I guess someone told the artist something about the book, but I'm pretty sure:
- Nobody in Europe dressed like that at the time.
- Nobody, even Europeans, in China, Tibet, or India dressed like that at the time.
- That if the main character showed up next Halloween, appropriately dressed for your "Come as a clichéd vampire" themed party, he still would not be dressed like that.
